Thinking about putting a LiftMaster 85870 on your garage? Here's how Farnsworth handles it.
You don't need to track down the LiftMaster 85870 yourself. We stock and source LiftMaster openers for our clients and bring the right one to your home.
As a belt drive, the LiftMaster 85870 runs quietly — but it still needs the rail squared, the belt tensioned correctly, and the safety system dialed in. A rushed install is the #1 reason a quiet opener turns noisy.
We balance the door, set the travel limits and force, test the safety reverse, program your remotes and the myQ app, and walk you through everything before we leave.

A garage door opener is easy to ignore until it strands you. If any of these sound familiar, it's worth a conversation:
The LiftMaster 85870 brings smartphone control and modern security — and we can have it installed before you know it. Learn more about opener repair & replacement, or call (602) 935-9766 and we'll tell you honestly whether a repair or a replacement makes more sense for your door.
Yes. We source, install, and service the LiftMaster 85870 across Phoenix, Mesa, Gilbert, Chandler, Queen Creek, Scottsdale, Tempe, San Tan Valley, and the rest of the East Valley. You don't need to buy the opener separately — we stock and bring it to you.
Both. Whether your LiftMaster 85870 needs a repair, a tune-up, or a full replacement, Farnsworth handles it. We work on this model regularly and carry the common parts.
